ABSTRACT:
A locking mechanism for connecting the bow of a boat to the staff of a boat-trailer. A horizontal bar is connected at one end of a staff and extends toward the rear of the trailer. This bar has a notch near the rear end. A swinging lock arm is pivotally attached to the horizontal bar and in the free position extends above and below the bar. A holding bar frame is attached to the bow of the boat and is substantially U-shaped with the open at the bottom. A round holding bar extends across the open end of the frame. A rolling bar is carried by a stop and release bar assembly which is guided up and down vertically by slots in the side members of the frame. When docking, the horizontal bar and swinging lock arm goes through the space between the round holding bar and the movable rolling bar. As soon as the horizontal bar passes through this space the swinging arms drop down and form a locking T-shape. They can only be released by pulling up on the movable bars so that the horizontal bar can be moved with respect to the holding bar frame.
